Social/dialogical roles of social robots in supporting children's learning of language and literacy-A review and analysis of innovative roles

Barbara Bruno

One of the many purposes for which social robots are designed is education, and there have been many attempts to systematize their potential in this field. What these attempts have in common is the recognition that learning can be supported in a variety of ...

A Model for the Representation of the Extraversion-Introversion Personality Traits in the Communication Style of a Social Robot

Barbara Bruno

Personality is one of the most important factors in human interactions, which retains its importance in human robot interactions with social robots. This work focusses on the varied linguistic strategies which characterize the personality traits of extrave ...

Questioning Wizard of Oz: Effects of Revealing the Wizard behind the Robot

Pierre Dillenbourg, Barbara Bruno, Jauwairia Nasir

Wizard of Oz, a very commonly employed technique in human-robot interaction, faces the criticism of being deceptive as the humans interacting with the robot are told, if at all, only at the end of their interaction that there was in fact a human behind the ...

Modelling the sustainability of a primary school digital education curricular reform and professional development program

Francesco Mondada, Barbara Bruno, Jessica Elke Dehler Zufferey, Laila Abdelsalam El-Hamamsy, Morgane Solène Denise Chevalier, Sunny Jonathan Jean-Jacques Laurent Avry, Emilie-Charlotte Monnier

Sustaining changes in teachers’ practices is a challenge that determines the success of curricular reforms, from which Digital Education (DE) is not exempt. As the literature on sustainability is considered “scarce” and “scattered”, long-term studies model ...

Personalized Productive Engagement Recognition in Robot-Mediated Collaborative Learning

Barbara Bruno, Jauwairia Nasir

In this paper, we propose and compare personalized models for Productive Engagement (PE) recognition. PE is defined as the level of engagement that maximizes learning. Previously, in the context of robot-mediated collaborative learning, a framework of prod ...

Quantitative analysis of the correlation between body posture quality assessment scores and handwriting quality measures

Pierre Dillenbourg, Barbara Bruno, Daniel Carnieto Tozadore, Chenyang Wang

Various technological applications for body posture correction have been proposed in order to improve handwriting or facilitate its learning for children, under the assumption that a better posture promotes better handwriting. However, very little research ...

How a Social Robot's Vocalization Affects Children's Speech, Learning, and Interaction

Barbara Bruno, Aditi Kothiyal

A wider incorporation of robots into classrooms is hampered by current technological limitations on full autonomy in social robots. Automated speech recognition, for example, a key enabler for vocal communication, is still unable to perform with sufficient ...

What if Social Robots look for Productive Engagement?

Pierre Dillenbourg, Barbara Bruno, Jauwairia Nasir

In educational HRI, it is generally believed that a robots behavior has a direct effect on the engagement of a user with the robot, the task at hand and also their partner in case of a collaborative activity. Increasing this engagement is then held respons ...

WriteUpRight: Regulating Children’s Handwriting Body Posture by Unobstrusively Error Amplification via Slow Visual Stimuli on Tablets

Pierre Dillenbourg, Barbara Bruno, Daniel Carnieto Tozadore

Maintaining a proper body posture during interactions with educational tablet applications is crucial for children's physical well-being and task performance, especially considering digital tablet's increasingly pervasive use in classrooms. In this work we ...

The competent Computational Thinking Test: Development and Validation of an Unplugged Computational Thinking Test for Upper Primary School

Francesco Mondada, Barbara Bruno, Jessica Elke Dehler Zufferey, Laila Abdelsalam El-Hamamsy

With the increasing importance of Computational Thinking (CT) at all levels of education, it is essential to have valid and reliable assessments. Currently, there is a lack of such assessments in upper primary school. That is why we present the development ...

Is There ‘ONE way’ of Learning? A Data-driven Approach

Pierre Dillenbourg, Barbara Bruno, Jauwairia Nasir

Intelligent Tutoring Systems (ITS) are required to intervene in a learning activity while it is unfolding, to support the learner. To do so, they often rely on performance of a learner, as an approximation for engagement in the learning process. However, i ...

Participatory design of a social robot and robot-mediated storytelling activity to raise awareness of gender inequality among children

Barbara Bruno

Gender inequality is a widespread problem in our society. It can manifest itself in many ways and contexts, and starting as early as primary school. While an increasing number of initiatives aim at tackling gender biases and inequalities, few of them are a ...

AlloHaptic: Robot-Mediated Haptic Collaboration for Learning Linear Functions

Pierre Dillenbourg, Barbara Bruno, Wafa Monia Benkaouar Johal, Aditi Kothiyal, Hala Khodr

Collaborative learning appears in a joint intellectual efforts of individuals to understand an object of knowledge collectively. In their search for understanding the problems, meanings, and solutions, learners employ different multi-modal strategies. In t ...

A Case for the Design of Attention and Gesture Systems for Social Robots

Barbara Bruno, Daniel Carnieto Tozadore, Utku Norman

The success of social robots, even (or, especially) in use cases as simple as "manning" a booth to promote a product in a shopping mall, depends on their ability of interacting with humans in a timely, effective and enjoyable way. In this paper we present ...
